guys got a 2014 300 brute force its my kids i noticed today when he parked it that it was leaking transmission fluid pretty bad so i crawled under the quad to find that the belt cover on the left side was soaked on the 300 it has a tube with a catch can from the top of the belt cover to vent it i guess? but i removed the catch can to find it full of oil question is where and how can oil get into the cover?

 

You have a bad transmission seal...most likely...


Was the vent plugged? Excess pressure could have pushed the fluid by the seals as well...
